ASHBURN, Va. (AP/ABC7) - Washington Redskins coach Mike Shanahan says "right now it looks good" that Robert Griffin III will be able to play Sunday against the Minnesota Vikings.
Shanahan said Griffin was experiencing no dizziness, headaches or vomiting Monday, a day after the No. 2 overall draft pick suffered a concussion in a loss to the Atlanta Falcons.
Shanahan emphasized that Griffin will have to go through a series of tests to satisfy the NFL's return-to-play protocol. If there are any setbacks during the testing, the coach almost certainly will start Kirk Cousins or Rex Grossman against the Vikings.
Griffin was knocked out in the third quarter against the Falcons on a legal hit by linebacker Sean Weatherspoon.
Football insiders say NFL officials are also paying close attention to how this situation is handled following recent scrutiny over the treatment of concussions in the league.
Raymond Solano, a chiropratic sports physician in Falls Church, said, "In his case, obviously, his bell got rung. They did the right thing, and they sat him out."
Solano said mild concussions usually take seven to 10 days to resolve themselves, adding it could be two to three weeks before Griffin is back in games.
